The sihconized epoxy coatings exhibited exceUent corrosion protection on the steel surfaces, and hence the Bode plot showed a very high resistance in the order of 10 x cm

This minimum corrosion resistance offered by polyamidoamine cured systems may be explained due to the formation of intermolecular hydrogen bond, which is influenced by polar amide group of polyamidoamine curative [60]. The high corrosion resistance offered by aromatic amine systems may be attributed to the formation of intercrosshnking network structure and their rigid nature.
